If heating only I use Sinope thermostat. They are simple. They have line voltage, low voltage and electric floor heating. They have WiFi and zigbee. But they do not support AC. I have them because I have radiant heat with floor sensors. They were the only company I could find that were zigbee with floor sensors. TH1400ZB
